Dear all,
Anybody knows about the difference amongst various spline smoothers,
specifically in R, 'bs' (by default a cubic spline), 'ns',
smooth.spline with roughness penalty along with many other smoothers? I've
consulted serveral books like 'S-plus Guide to Statistics' by Mathsoft,
Ripley and Venables' Splus book and Eubank's Spline Smoothing, but I was
still looking for a substantial discussion on the difference in using these
smoothers. I try to put the question clear or maybe somebody can provide some
sources for reference. If possible, I'd also like to see some comments for
practice.
Regards,
LS
